Dumas-bulb technique

In the Dumas-bulb technique for determining the molar mass of an unknown liquid, you vaporize the sample of a liquid that boils below 100 °C in a boiling-water bath and determine the mass of vapor required to fill the bulb (see drawing, next page). From the following data, calculate the molar mass of the unknown liquid mass of unknown vapor, 1.012 g volume of bulb, 354 cm pressure, 742 torr temperature, 99 "C.
